It is a berry type fruit with chromosome number 2n=2x=24. It was originated in the Andes region. Tomato is a rich source of water, vitamins and lycopene. The tomato crop is affected by various abiotic and biotic stresses. Nematode infection is one of the prominent biotic stresses responsible for crop loss. The aim of this research was to evaluate resistant and susceptible tomato genotypes, to elucidate certain resistant genes, during the nematode infection.EnglishThesis
